How Often Should I Change My Toothbrush?

Practically everything we own is subject to at least some wear and tear, and your toothbrush is one of them. As your toothbrush wears out, the effectiveness to clean your teeth will also be affected. 

The process is gradual and you may not be able to notice how far your toothbrush has gone, which is why you should change your toothbrush regularly. So in order to see improvements in your oral health let’s answer the question, “how often should I change my toothbrush?”

When To Change Your Toothbrush

The American Dental Association (ADA) suggests that you should replace your toothbrush every three to four months. This should be done whether you have a regular or electric toothbrush. Consider two reasons for doing so.

Worn out bristles

The bristles on your toothbrush will get softer and fray slightly after each time you use them. You may not notice this from day to day but it’s obvious when you replace your toothbrush with a new one.  Worn bristles are not very good at removing plaque from your teeth.


You should consider the hygiene of your old toothbrush too. Bacteria love to hide inside the bristles. Rinsing the brush under running water and drying it after use can go a long way in reducing the level of bacteria. Whilst traveling be sure to protect the brush head of the toothbrush by covering it. Changing your toothbrush after recovering from a respiratory illness will also help to avoid reinfection.

Bottom Line: If you have lost track of how old your toothbrush is and the bristles have become frayed or darker in color (possibly due to mold) then you should change your toothbrush.

What Happens If I Don’t Change My Toothbrush Often Enough?

Let’s think back to the two reasons above as reasons why you should replace your toothbrush regularly.

If your toothbrush is frayed, it cannot remove plaque effectively. A buildup of plaque can cause gingivitis or develop into periodontitis which is a common cause of tooth loss.

Also, your oral health will suffer if you expose your mouth to high levels of bacteria.

What Toothbrush Should I Get?

It’s best to select a toothbrush that will suit your specific needs. Your dentist is in a good position to help. Usually, dentists will suggest softer bristles over harder ones to avoid any potential damage to your teeth and gums. It’s normally suggested that the toothbrush has a head large enough to cover two teeth at the same time.

You could also consider using an electric toothbrush. Some find it beneficial in the removal of plaque stains and reducing gingivitis.
